Non woven fabric has the advantages of high filtration​ efficiency, large dust holding capacity, long service life, and low manufacturing cost. It is recognized as one of the best air filter materials. Non woven filter material is one of the most widely used air filter materials. air filter media The demand for non woven air filter materials is increasing year by year and has become the main air filter media. Compared with traditional filter materials, it has the advantages of high production efficiency, short production process, low production cost, and wide range of raw materials. Common non woven materials are made of polyester and polypropylene fibers by mechanically reinforcing the fiber mesh, which has a good filtering effect. air filter media The production process can be roughly subdivided into needle punched non woven fabric, spunbond non woven filter fabric, spunlace non woven filter fabric, and meltblown nonwoven fabric. The difference in production processes also determines the difference in use and filtration performance.
